Never complain and never explain.
Go for it now. The future is promised to no one.
Know or listen to those who know.
Only the educated are free.
If you can dream it, you can do it.
Quality is not an act, it is a habit.
Always desire to learn something useful.
The dog that trots about finds a bone.
Either you run the day or the day runs you.
After a storm comes a calm.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
